Method for calculating the side slip angle of a vehicle wheel with a tilted rotation axis

The paper presents a reserach related to studying elastic properties of the elastic vehicle wheel as a deformable body. It considers a problem of mathematical simulation of the wheel slipper angles at the rotation axis tilt. Slipper deformation theory and laboratory experiments form the research basis. Mathematical dependence for determining the elastic wheel slipper with a rotation axis tilt is identified. A method for computing the elastic wheel lateral slipper with a rotation axis tilt is developed. Mathematical dependencies are obtained of the slipper angle on coefficients of the normal and lateral rigidity alteration at a given angle of the rotation axis tilt. The paper establishes that the wheel slipper is decreasing with the wheel rotation axis internal tilt of the vehicle axle. It shows that the slipper angle could be reduced by with the rotation axis tilt of the wheel under study to the maximum permissible angle under the tire wear conditions.
